General Instruction Characteristics Section 1-1
The following diagram shows the characters that can be expressed in ASCII.
Note The following instructions are executed even when the input conditions are
OFF. Therefore, when indirect memory addresses are specified using auto-
incrementing or auto-decrementing (,IR+ or ,IR-) in an operand of any of
these instructions, the value in the Index Register (IR) is refreshed each cycle
regardless of the input condition (increases or decreases one every cycle).
This must be considered when writing a program.
